The biliary-brachial muscle (m.coracobrachialis) begins at the apex of the coracoid scapula of the scapula, passes into a flat tendon that attaches to the humerus below the crest of the small tubercle at the level of the tendon attachment of the deltoid muscle. Part of the muscle bundles is interlaced in the medial intermuscular septum of the shoulder.
Function of the beak-brachial muscle: flexes the shoulder in the shoulder joint and leads it to the trunk. Participates in turning the shoulder outward (if the shoulder is pierced). If the shoulder is fixed, the muscle pulls the scapula forward and down.
Innervation of the coracoid-brachial muscle: musculocutaneous nerve (CV-CVIII).
Blood supply of the beak-brachial muscle: anterior and posterior arteries surrounding the humerus.
